In parts of the Spree Forest biosphere reserve, an enchanting landscape of rivers and lakes, the mail is still delivered by small wooden boats. It is also where the famous Spree Forest gherkins are grown. The Niederfinow ship lift is a sight to behold and the oldest surviving construction of this kind in Germany. Spree Forest is paradise on water. Now, 25 years after the fall of the Berlin Wall, it is celebrating 20 years as a biosphere reserve.
